A beauty pageant that ­requires contestants to show some skin in the bathing suit portion has thrown out a competitor for showing too much of it.

Sophie Froment was dismissed from the Miss Universe Canada pageant on Saturday after some steamy television commercials she did for Ashley Madison — a dating website for men and women seeking an affair — were leaked to organizers.

The company’s website advertises a 100 per cent “affair guarantee.”

Last December, its “Life is short. Have an affair” advertising campaign was rejected by the TTC’s advertising review committee because it didn’t meet community standards.

Although Froment, a 21-year-old law student, is currently featured in a U.S. television commercial for the company wearing lingerie, the ads in question were never broadcast. But someone — Froment says she doesn’t know who — posted them online.

In one commercial, Froment is topless and lying on her stomach on a bed with a man. In another, she’s kissing him.

A statement on the Beauties of Canada website, which produces the Miss Universe Canada, says Froment was dismissed because she “made some career choices that are not compatible with the image of women that our organization tries to promote; and which would disqualify her from representing Canada at the 2010 Miss Universe Pageant.”
